How can I implement a Progressive Web App (PWA)?

To implement a PWA, start by ensuring your web app is served over HTTPS, then create a web app manifest and a service worker.

What is a web app manifest?

A web app manifest is a JSON file that provides metadata about your app, like its name, icons, and start URL.

How do I create a service worker?

You can create a service worker by writing a JavaScript file that listens for events like 'install' and 'fetch'.

Can you give me an example of a service worker?

Sure! Here's a simple example:

self.addEventListener('install', (event) => {
  console.log('Service Worker installing...');
});

self.addEventListener('fetch', (event) => {
  event.respondWith(
    caches.match(event.request)
      .then((response) => {
        return response || fetch(event.request);
      })
  );
});
